American Correctional Association

The American Correctional Association (ACA; called the National Prison Association before 1954) is a private, non-profit, non-governmental trade association and accrediting body for the corrections industry, the oldest and largest such association in the world. The organization was founded in 1870 and has a significant place in the history of prison reform in the U.S.

ACA accredits over 900 prisons, jails, community residential centers (halfway houses), and various other corrections facilities in the U.S. and internationally, using their independently published standards manuals. Approximately 80 percent of all U.S. state departments of corrections and youth services are active participants. Also included are programs and facilities operated by the Federal Bureau of Prisons and the private sector.

Shane Bauer of ''Mother Jones'' wrote that the ACA functions as "the closest thing [the United States has] to a national regulatory body for prisons" in addition to being the American correctional industry's trade association. Provided by Wikipedia
